Rectangular 01 561 7656 4074-07 8 17 82— lug 17mm

The lug width measures 17 millimetres, calculated from the inner channel of each lug, shoulder to shoulder. This is a rare specification requiring bespoke strap solutions. To measure accurately, position a ruler in the recessed interior of each lug: this width ensures precise compatibility without lateral play or binding.

Selection depends on wear context. For formal settings, we recommend dark brown or black alligator, or vegetable-tanned calf in burgundy or cognac tones. For lighter daily use, a grey or olive NATO, or black rubber, repositions the watch as a versatile instrument. The rectangular case geometry accommodates both solemnity and pragmatism equally.

Obtain a spring bar tool. Position the watch dial-up, locate each lug, and with gentle lateral motion, compress the baionette spring toward the watch body. The old strap will release. Insert the new strap's lug first on one side, then flex the case gently to align the second side and re-engage the spring. Verify both sides lock firmly.

Yes, provided it is compatible with the 17-millimetre lug width. Many generic market straps are dimensioned for 18mm or 20mm and will not deliver the constructive precision required. Select bespoke straps explicitly made for 17mm lugs, where the lug is built to tight tolerances and the <a href="/pages/termine-glossario/deployante">deployante</a> or folding clasp is dimensioned correctly for case width.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily wear, assuming conscientious care (avoiding prolonged moisture, no twisting stress). Vegetable-tanned leather ages visibly, developing authentic patina, versus aniline finishes. NATO or rubber straps extend lifespan to 5-7 years but accrue less aesthetic character over time.
